I wrote earlier about publishing zones with djbdns. That post didn’t cover zone sync between djbdns servers. This small guide assumes we’ll be syncing all zones between two servers, s01 and s02.

Doing this by using ssh keys instead of regular login has the benefit of not asking for your password when syncing the zones. You can skip this step if you want.

On s01, do the following.

# ssh-keygen -t dsa
# scp ~/.ssh/id_dsa.pub s02:.ssh/authorized_keys

The edit the Makefile file in the root folder of djbdns on s01 and make it look like this.

remote: data.cdb
        /usr/bin/rsync -az -e ssh data.cdb s02:/etc/tinydns/root/data.cdb

data.cdb: data
        /usr/bin/tinydns-data

Adjust all paths according to your own setup.

Running make will now sync your zones to s02.

# make
/usr/bin/tinydns-data
/usr/bin/rsync -az -e ssh data.cdb s02:/etc/tinydns/root/data.cdb
#
